"Blindsight is a tour de force, redefining the First Contact story for good. Peter Watts' aliens are neither humans in funny make-up nor incomprehensible monoliths beyond human comprehension - they're something new and infinitely more disturbing, forcing us to confront unpalatable possibilities about the nature of consciousness. It'll make your skin crawl when you stop to think about it. Strongly recommended: this may be the best hard SF read of 2006."
